A team of international researchers has introduced an innovative approach to detecting dark matter, leveraging atomic clocks and ultra-stable lasers to investigate the enigmatic substance believed to hold galaxies together.
University of Queensland PhD student Ashlee Caddell co-led the study in collaboration with Germany’s Physikalisch-Technische Bundesanstalt (PTB), using high-precision atomic clocks and cavity-stabilized lasers to search for dark matter in an unprecedented way.
“Despite extensive theories and experimental efforts, dark matter remains elusive, even though we consider it the ‘glue’ that binds the galaxy,”…
